The reporting of Mineral Resources and Mineral Reserves for Implats’ South African operations is done in accordance with the principles and guidelines of the South African Code for Reporting of Mineral Resources and Mineral Reserves (SAMREC Code).

SAMREC was established in 1998 and modelled its code on the Australian Code of Mineral Resources and Ore Reserves (JORC). The first version of the SAMREC Code was issued in March 2000 and adopted by the JSE Limited (JSE) in the Listings Requirements later in the same year; this was similarly the basis for the JSE’s Ongoing Reporting Requirements which were promulgated in 2005.

The SAMREC Code has been under review since 2004 and an updated code, SAMREC 2008, was promulgated by the Southern African Institute of Mining and Metallurgy (SAIMM) and the Geological Society of South Africa (GSSA) in June 2008; the JSE subsequently incorporated this new version into its listing and reporting requirements.

Zimplats, as an Australian Securities Exchange-listed company, reports its Mineral Resources and Ore Reserves in accordance with the JORC Code. Mimosa Investments Limited, a Mauritius-based company, does not fall under any regulatory reporting code but has adopted the JORC Code for its reporting.

The definitions contained in the SAMREC Code are either identical to or not materially different from international definitions. International definitions for Mineral Resources and the Indicated and Measured Mineral Resource sub-categories, and the definitions for Mineral Reserves and the Probable and Proved Mineral Reserve sub-categories, are the same as those found in the SAMREC Code.

Various Competent Persons, as defined by the SAMREC and JORC codes, have contributed to the summary Mineral Resource and Mineral Reserve figures quoted in this report. As such, these statements reflect the estimates as compiled by teams of professional practitioners from the various operations, shafts and projects.

Registration No. 400015/88, a full-time employee of Implats, assumes responsibility for the Mineral Resource and Mineral Reserve estimates for the Implats group.
